Peste des petits ruminants is a systemic and highly contagious disease in goats and sheep. Causing agent (Peste des petits ruminants virus) is a Morbillivirus in Paramyxoviridae. The disease is enzootic in Iran and the west of Iran especially Kermanshah province has a lot of serious problems in this case. Therefore, in this study domestic small livestock were investigated by both serological (Competitive ELISA) and molecular (RT-PCR) methods in Kermanshah. The aim was comparison of sensitivity of these methods in diagnosis of PPR in early stage especially before diarrhea onset. By RT-PCR assay, 23 from 30 samples turned out negative and 7 has become positive (23.33% positive). 2 samples from sera related to those 7 animals were negative in ELISA test and the other 5 sera were positive. So, overlapping percent of the assays is 71.42. Moreover, sensitivity of PCR is 6.70% more than cELISA. In spite of more costs of the PCR than ELISA, accuracy and speed of PCR is a specific advantage which suggests virus isolation and competitive ELISA can be substituted by PCR to control and prevention of the illness. Regarding to the results, it is suggested to do more investigations on the prevalence of the disease in Iran to gain clear information about prevalence and risk factors of the infection in different parts of the country.

The aim of this study was to compare the total protein levels in serum of veteran exposure to sulfur mustard (SM) which was used in the Iran-Iraq war. In this study, 35 patients exposed to mustard gas (case group) and 35 healthy subjects (control group) were evaluated. The total protein concentration was measured by Bradford method. The average amount of protein in serum exposure to sulfur mustard (patients) in compared with a control group, showed no significant differences (p>0.05). The observed inflammatory reaction in the lungs and eyes exposed veterans with sulfur mustard gas and the total protein in the serum of healthy individual veterans did not show significant differences in inflammatory factor. Therefore, it should be the amounts of inflammatory factors in local (lungs and eyes) were high and the systemic inflammatory factors may be increased.

Abstract
Fish meat has high nutritional value and putrescence. For this reason, it is very important increase the shelf life and fish meat quality. In this study tried to go up the shelf life and quality fish meat by ozon ice. The number of Rainbow trout with weight 300±10 purchased and transferred to the Mashhad laboratory (Iran) immediately. The fish was divided into four groups, control (A), dose of 3g (B) 4g (C) and 5g of ozone per 50 kg ice with the brine 5% (D). Daily to the fourteenth day of corruption were used on the WHO chart. Moreover sampling of skin, meat and gill tissue was done every day to the 12th day for check bacterial by (PCA) cultured. The amount of histamine (ELISA method), peroxide (PV) (Egan method) and TVN (Kldal distiller method), was obtained respectively. The results showed that A sample (control) had corrupted the most number of bacteria in depth and surface have existence ten days significantly (P <0.05). Amounts of peroxide and TVN in B sample lower than to the other fish samples and had no significant increased (P 0.05). Histamine changes was not significant in all samples (P<0.05) and all of the fishes ozone treated have better maintenace and quality. Thus it can be infered that ozone is an effective mater to increase the durability of fish.

Abstrac Effects of stress due to transportation on the common carp (Cyprinus carpio) broodstock from ponds to the hatcheries in three intervals include immediately after the catching, 2 hours for transfer and 24 hours after transportation on changes in levels of cortisol, glucose, sex steroids (testosterone and estradiol) and blood factors were analyzed with sampling from 30 broodstock. Results showed that cortisol levels rose quickly after the catching (625 ng per ml) and significantly decreased after 24 hours (409 ng per ml) (P0.05). Testosterone and estradiol levels were significantly different among the three intervals, in which the highest values were observed after the catching and significantly decreased with time (P0.05). Also, 24-hour maintenance of breeder’s improved the blood parameters. Based on the results, the transportation of common carp broodstock had negative effects on cortisol, steroid hormones and some blood parameters (erythrocyte and hemoglobin values), thereby it is necessary to the maintenance of broodstock (even in the short-term transfer) in hatcheries ponds.

The aim of this study is to determine the level of people’s awareness and willingness towards the protection of Persian wild ass (Equus hemionus onager), to recommend solutions that can improve management and conservation of this species. In this descriptive-analytical study, 660 people from Fars province were chosen via the clustered method. A questionnaire comprising items about the people’s demographics as well as their knowledge and cooperation regarding to protection of Persian wild ass was completed for all the study population through interviews. Subsequently, descriptive statistics, x2, t-test and Kruskal-wallis test were employed for analysis using SPSS Software (version 21). Result showed that, 63.6 percent of the cases had poor knowledge and 40.5% had no desire to support of this species. On the other hand, there were a significant correlation between knowledge and sex and awareness and age (P < 0.05). The highest level of knowledge was found among those with university levels of education. There was not a significant correlation between willingness to supports of Persian wild ass and educational levels (P < 0.05). Consequently, given that the majority of the people’s under study had poor knowledge and function about Persian wild ass protection and conservation, it seems advisable that regular and systematic training programs be devised in relation to population decrease prevention strategies such as practical classes on protection of Persian wild ass.

Abstract According to many literatures marsh frog (Rana ridibunda) probably has the potential to become a commercial species which was exploited at least once about 30 years ago in Anzali wetland region.The global decline of amphibians urgently calls for a better understanding of amphibian population dynamics. Study of population size of marsh frog which has not been yet conducted in Gorigol wetland was carried out using the mark-recapture method. The objective of this study was to establish the population size of a population for contribution to the rather limited knowledge of the ecology of the species, which is widespread in Iran. We could not to achieve our main goal (i.e. estimating of population size) due to lack of enough recapture data. But, this study indicated that it is useful to conduct the robust design to increase the recapture probability of individuals. According to our results, a primary period needs to be one week, and within the week, the secondary periods should be the series of two nightly or more samples.

Abstract In order to investigation the effect of different levels of Onion powdr (Allium cepa) on growth performance, survival, fillet composition and hematological parameters of rainbow trout, a completly randomize design with six treatments and three replicates (15 fish in each replicate) were conducted for eight weeks. Experimental dietary included 0, 0.5, 1, 2, 3 and 5% onion powder. All the rainbow trout fishes that have 60± 1 weight adobeted with enviromental condition for two weeks. All of the data was analyze with SPSS software. The results of this experiment showed that onion powder significantly increase weight gain at 1 percent level in comparison with control treatment (P0.05). Results showed that the highest level of white blood cells was observed in 5% level of onion powder and lower level was observed in Control (P0.05). Body coposition (protein, fat, moisture and ash) also showed no significant differences among treatments (p>0.05). Indeed, these results showed that onion powder at higher levels did not any adverse effect on other parameters.

Colour pattern polymorphism is more hereditary and subject to selection. Most of anuran species showed significantly colour or dorsal pattern polymorphisms, thus provide a very good system in which to survey questions pertaining to the evolution and maintenance of polymorphisms. 25 species of anuran amphibians presented that they have been seen in color polymorphism and Rana (Pelophylax) genus have the most variety. In most anurans, polymorphism is caused by the presence or absence of spots on the back of their bodies. Color variations can include skin of the whole body or part of It,s. In this research for the survey of polymorphism marsh frog Pelophylax ridibundus, dring six month of field work in the sampling areas (since March 2013 to August 2013), 200 specimens were collected from six stations (Astaneashrafiye, Siyahkal, Lahijan, Langerood, Roodsar and Amlash) in east of Guilan province. Sampling carried out using the handle tour. Samples were transferred alive to the zoology lab of Tonekabon Branch, Islamic Azad University, Then different morphs and their characteristics were recorded, based on the number and location of spots, presence or absence of the mid dorsal stripe and the amount of green in the back, out of 25 morph were identified, That it variety could be due to ecological factors, to escape from the hunter or the prey or due to genetic factors.

160 one-day-old male broiler chicks (Ross308) in 2 groups of 4 replicates were studied in each group20 chicks for each replicate were used. One group of these birds was rose in normal temperature (NT treatment) and the other group was raised in cold temperature induce PHS and heart failure (CT treatment). Glutathione peroxidase (GPX), superoxide dismutase SOD (, total antioxidant status (TAS) and malondialdehyde (MDA) content of both plasma and liver were determined at days 21 and 42 At the end of the experiment (day42), 2 chicks from each replicate were randomly selected and slaughtered. The heart was removed and the right ventricle was dissected away. The ratio of right ventricle weight to total ventricle weight (RV/TV) was calculated. Results showed that MDA content in plasma and liver of CT birds was greater than that of NT birds at day 21 and 42. GPX activity in plasma and liver of CT birds at day 21&42 and SOD activity in plasma at day 42 were lower than that of NT birds. Furthermore, birds of NT treatment had a higher plasma TAS (P<0.05) at both ages. Moreover, RV/TV ratio at day 42 and mortality in total period were significantly higher in CT birds.

Main purpose of the present research was to study the effects of replacing green algae with agricultural by-products on growth and survival rate of Artemia franciscana. The study was a 4×2 factorial experiment conducted as a completely randomized design. Factors were different types of diet (wheat bran, rice bran, mixture of wheat and rice bran and the alge (Dunaliella salina) and probiotic inclusion level (0 and 10% of the daily meal). All treatments were in triplicates and the experiment lasted for 17 days post hatch. At the end of the trial, growth and the survival rates were calculated. Results showed that total length of Artemia fed wheat bran and alge with probiotic (8.20±0.03 mm) was the highest and that of group fed wheat and rice bran and algae (6.76±0.03 mm) was the lowest (p0.05). According to the results, it seems that unicellular algae can be replaced with easily affordable agricultural by-products and artemia could convert waste to wealth for the sake of environment and expanding aquaculture enterprise.

Abstract Different organisms like aquatics are constantly exposed to pesticide residues, this study's overall assessment patho-biological changes in gills and livers of Capoeta capoeta gracilis during exposure to butachlor pollutant. First of all the 96-hour lethal concentration of the toxin was calculated as 46.2 mg per liter. Then, 96 fish were divided into four groups: one control group and three experimental groups (with concentrations of 0.2, 0.4, and 0.8 mg l-1) and were exposed for 2 weeks. In the end point, histological changes were studied by hematoxylin and eosin staining method in light microscopy. Lethal concentration of this toxin was 2.46 mg/l that means moderate toxicity of this species. There was many histological changes in the gills of fish treated with butachlor include: hyperplasia, shortening the secondary lamella, edema, fusion, hemorrhage and atrophy in compared to the control group. Treatment with liver butachlor cause obstruction, dark granules, necrosis, and bile stagnation and sinusoid dilution in studied fish. The results of this study showed that in both studied organs with increase of toxin concentration, more severe tissue damage was observed, so gill and liver tissues of this fish could be used as an appropriate biomarker for pollutant measurement.

Abstract The Sugarcane grasshopper (Chrotogonus trachypterus) is one of the most important and indigenous and harmful pest of field crops in Sistan region of Iran and cause considerable damage especially during seedling stages. We conducted this study in order to introduction of a biocontrol agent to C. trachypterus in a completely randomized designs and factorial experiment with three replications using topical application under laboratory conditions. For inoculations, after the preliminary experiments, five fungal suspensions prepared at consecrations of 1×104, 1×105, 1×106, 1×107 and 1×108 conidia mL-1 in distilled water containing 0.05% Tween-80®. Grasshoppers typically inoculated under the pronotal shield using a Hamilton microaplicator. Control treatment were treated with distilled water containing 0.05% Tween-80® as surfactant. The corrected cumulative percent mortality was recorded daily until 15 days after inoculations. Percentage of insect mortality was analyzed using (log-probit) methods.Results showed T. harzianum was pathogenic to adult insects and insect mortality increased with increasing concentrations. The highest and lowest mortality observed at 108 conidia mL-1 and 104 conidia mL-1 with a 75 and 25 percent respectively (p50value was 1.01×106conidia mL-1. This is the first report of the pathogenicity of T. harzianum to the grasshopper, C. trachypterus.
